NEW BEDFORD, Mass. -- Two foreign nationals have been arrested on immigration violations in the Massachusetts town where police say the surviving Boston Marathon bombing suspect may have once lived.

Immigration and Customs Enforcement said Saturday that Homeland Security Investigations agents had arrested two people in New Bedford.

An ICE spokesman would not comment on the people who were arrested or if they are connected to bombing suspect Dzhokhar Tsarnaev (joh-KHAR' tsahr-NEYE'-ehv). The University of Massachusetts at Dartmouth student remains hospitalized after exchanging gunfire with police Friday.

ICE did not say whether they are suspected in any other crimes. A federal prosecutor's spokeswoman declined comment.

New Bedford police said federal authorities searched off-campus housing near the school Friday and took three people in for questioning. Police say Tsarnaev may have lived at the complex.
